Diesel RVs: Re: [diesel_mercedes] Automotive Battery Life

There also is the reserve capacity. I've noticed sales people selling
CCA's. Some of them have the capability of putting out the amperage,
but don't have the reserve to keep delivering it. Sometimes you can't
find the reserve rating on the battery. It is usually listed on marine
deep cycle batteries. The best way I know is:

If you pulled out a large battery and put in a small one, you have lost
reserve power. But some manufacturers are recognizing that, and adding
plastic fillers to make the batteries the same size. You can tell this
by weighing the batteries. The old large one is mostly lead. The one
with less reserve will have more plastic (lighter).
